Miniature rose plant named ‘SAVared’

ABSTRACT

‘SAVared’ is a new and distinct variety of miniature rose plant primarily identified by the very strong fragrance in a red miniature rose. The plant is upright with medium to dark green, matte foliage. The attractive flowers may occasionally have exhibition rose form. They are held well above the plant, borne singly on long stems and in small sprays, and good as cut flowers.

Genus/species: Rosa hybrida ‘minima’.

Varietal denomination: ‘SAVared’.

Commercial class: Miniature rose.

CROSS REFERENCE

This new invention relates to a new and distinct variety of hardy,dwarf, bush type rose plant, bearing some resemblance to ‘BENfebu’ (U.S.Plant patent application Ser. No. 10/318,843 with a filing date of Dec.13, 2002). The flowers of both cultivars are a similar shade of red,with 23 to 28 petals, with those petals being about as long as they arewide. Both cultivars are of an upright growing habit, reaching up to 30inches tall, with flowers primarily borne singly under similar growingconditions. The two primary differences between BENfebu and the newcultivar are that ‘BENfebu’ has more of its dark red flowers borne inclusters and that the reverse of these petals is flushed with whitewhile on this new cultivar, the dark red flowers are borne more oftensingly and on longer stems and the reverse of its petals is the near thesame shade of red as the top of the petals. Additionally, theanthocyanin coloration of the stems and foliage is mostly absent onBENfebu while it is always present and sometimes strong on the newcultivar.

The known relationship between these plants is that the miniature rosevariety, ‘Party Girl’ (U.S. Plant Pat. No. 4,598) is in the parentage ofboth plants in the second generation back, and the miniature rosevariety ‘Baby Katie’ (U.S. Plant Pat. No. 4,471) is in the thirdgeneration back for both plants.

BACKGROUND OF THE INVENTION

This present invention relates to a new and distinct variety of hardy,bush type plant of the miniature rose class. This new variety wascreated by me in a greenhouse in Rowley, Mass. by crossing the followingtwo rose plants:

The seed parent is ‘Taxi’ (not under patent protection).

The pollen parent is an unintroduced seedling of [‘Party Girl’ (U.S.Plant Pat. No. 4,598) by ‘SAVaspark’ (U.S. Pat. No. 9,799)] by‘MACgenev’, (U.S. Plant Pat. No. 8,279).

The main purpose of this breeding program is to produce unique miniatureroses with hybrid tea form. We are also trying to reintroduce fragranceinto roses along with disease resistance. Our ideal miniature rose wouldhave fragrance and excellent disease resistance, along with hardinessand exhibition, hybrid tea form blooms in abundance from late spring tolate fall.

To achieve this goal, various fragrant roses have been brought into thebreeding program which, besides fragrance, were chosen for diseaseresistance and hardiness and then for hybrid tea, exhibition form. Thoseroses are mostly hybrid tea roses and with a couple of floribunda. Theselarger fragrant roses are then crossed with miniature roses, chosen fortheir disease resistance, durability and quality of bloom production inhopes of producing fragrant, hardy, disease resistant, floriferousminiature roses.

To create this rose, I used the very fragrant, hybrid tea rose, ‘Taxi’,noted for its good disease resistance and hardiness, as the seed parent.The pollen parent was a seedling that was the result of crossing a veryfloriferous miniature seedling from earlier in the hybridizing program,by the very fragrant hybrid tea, ‘MACgenev’. This miniature seedling is,itself, fragrant and with tremendous bloom production and for thosereasons was chosen for this particular cross.

This present invention, like its seed parent, ‘Taxi’, has red flowerswith intense fragrance and with exhibition, hybrid tea form. Both plantshave an upright growing habit. The most obvious difference between thetwo is that the seed parent is an hybrid tea rose while the newinvention is a miniature rose. Although both roses are red, the newinvention is a bluer-red while the seed parent is more of an orange-red.

The pollen parent is a fragrant, apricot miniature seedling. Thesimilarities between this present invention and the pollen parent arethe petal count and the fact that both are fragrant and miniature roses.This present invention is different from its pollen parent in planthabit and color. The new invention is red flowering and of uprighthabit. The pollen parent has medium-apricot colored flowers and a morespreading plant habit.

Asexual reproduction by cuttings of this new variety in Rowley, Mass.,have shown root development to initiate in 1 to 2 weeks on cuttingstaken from new growth, depending on light and temperature, and thatthese rooted cuttings, grown on, show all distinguishing characteristicsto continually come true to form.

SUMMARY OF THE INVENTION

The present invention relates to a new and distinct variety of hardydwarf bush type rose plant of the miniature class; the variety beingprimarily characterized—as to novelty—by it's intense fragrance in a redminiature rose with hybrid tea type form.

The variety is further characterized by:

-   -   Flowers borne mostly singly on long stems, ideal for cutting.    -   Repeat of bloom from late spring to early autumn.    -   Matte foliage.    -   Flowers held above the foliage on long stems, suitable for        cutting.    -   A plant which grows and blooms both in the greenhouse and        outdoors in the garden or in large containers providing        decoration and fragrance.
